Intrinsic Safety for Hazardous Area

  • Chapter
  • First Online:
Wireless Communication in Underground Mines

Abstract

It is vital need to apply safety measures to the electrical apparatus used in explosive atmosphere as this impedes any damage to the property as well as reduces the risk of life of the workers on duty (Adams, 1990, 1991). There are various protection concepts deployed in sensitive and potentially explosive atmospheres. Among these, intrinsic safety (IS) offers the highest level of safety of entire explosion protection technique for electrical apparatus since it uses low voltage, low current, and low power. Intrinsic safety is a protection technique based on the restriction of electrical energy to a level below that which cannot cause ignition by either sparking or heating effects. It is achieved by limiting the amount of power available to the electrical device in the hazardous area. Thus, IS relies on the equipment being ignitior of a flammable gas, vapor, or dust that may occur in normal use, or under any conditions of fault likely to occur in practice. IS electrical circuits are designed with special consideration of proper printed circuit board (PCB) layout, minimum surface temperature, appropriate protection of electrical components, and suitable power supply to a device.
